Abstract
A transient, three-dimensional, four-field model is under development to deal with the premixing of large amounts of molten corium falling d own in the lower plenum of a PWR. This paper presents the main feature s of the code, written in as mechanistic a manner as possible, in orde r to provide best-estimate results. Calculations with a two-dimensiona l, three-field version of MC3D of two FARO tests are presented.
